I have had some similar problems with .keep files. I cloned a repo I created that had a branch that I wasn't interested in. I deleted the branch and then I could never get rid of the (large) number of objects in that pack until I deleted the .keep and repacked. I think there should be some way of forcing git to fix this sort of thing.

It gets even worse, I had pushed up the branch I wanted to get rid of to my hosted server and there was no way to get git to release that disk space. I had to have the hosting admin send me a tarball of the repo, extract it, delete the .keep file and repack it then send it back to him. I was fortunate enough to have a service that would let me do that.

Thanks, Govind.
